Abstract (en)
[origin: DE19957959C1] The piezovalve manufacturing method has a piezo flexure element (4) secured at its fixing end in a fixing body (26), before insertion in the valve chamber of a valve housing (13), with a contoured surface (24) of the fixing body brought into contact with a corresponding contoured surface (23) provided by the housing. The piezo flexure element is positioned by a rolling movement between the cooperating contoured surfaces, to bring its control section into contact with a valve seat (8) provided by the housing with a required force, before securing the fixing body in position, e.g. via an adhesive layer. An Independent claim for a piezovalve is also included.
